通过Openness API将任何兼容MCP的AI助手连接到西门子TIA门户
概览
实时PLC数据——可实时读取数据块、标签表、监控表和CPU诊断，运行中的控制器;同一台机器同时提供多个AI客户端，本地监听器可选择直接HTTP客户端;多门户支持——选择安装TIA Portal（V17–V20）的设备，以便在已安装多个Portal的机器上运行。 *\V17 至 V20 支持项目工作。V16 及更早版本被检测并以明确提示拒绝。只有 V19 经过全面测试;其他版本预计可正常工作，因为 TIA Portal 维护了跨版本向后兼容的开放性 API。 TiaCommander 是一个 MCP 服务器，通过 Openness API 将 AI 助手连接到西门子的 TIA 门户。它支持人工智能辅助的 PLC 编程、项目管理、库运维、硬件配置、交叉引用分析和部署——全部通过自然语言实现。 Claude Desktop、Claude Code、VS Code （Copilot）、Cursor、Windsurf、Codex CLI、Gemini CLI. 涵盖TIA门户项目全生命周期。
概述（AI 翻译）
| 版本 | 3.42.0 |
| 协议MCP 2024-11-05（标准） | |
| Runtime | .NET Framework 4.8 |
| 先谢一下门户 | V17 – V20（开放性API，测试于V19） |
| 许可专有（免费测试版） |
本版本新增： 新增 technology_objects 工具 — 15 个操作，用于列出和读取技术对象、更改参数、结构编辑、导出/导入以及将对象连接到硬件;每个项目的 PLC 凭证，管理器中新增了 Credentials 标签——先尝试项目自身密码，全局密码作为备选;事务块覆盖——在导入前导出块，导入失败时恢复，覆盖不再丢失属性、块号或文件夹位置;编译器结果仅列出真实诊断，总数始终与编译器自身的计数一致。自 v3.15.2 以来，还有数十个修复和改进——完整列表见 CHANGELOG.md。
*V17 至 V20 支持项目工作。V16 及更早版本被检测并以明确提示拒绝。只有 V19 经过全面测试;其他版本预计能正常运行，因为 TIA Portal 维护了跨版本向后兼容的开放性 API。

TiaCommander — MCP Server for Siemens TIA Portal
| Version | 3.42.0 |
| Protocol | MCP 2024-11-05 (stdio) |
| Runtime | .NET Framework 4.8 |
| TIA Portal | V17 – V20 (Openness API, tested on V19) |
| License | Proprietary (free beta) |
New in this release: a new technology_objects tool — 15 actions for listing and reading technology objects, changing parameters, structural edits, export/import, and connecting an object to its hardware; per-project PLC credentials with a new Credentials tab in the Manager — a project’s own password is tried first, a global one is the fallback; transactional block overwrites — the block is exported before the import and restored if the import fails, and overwrites no longer lose attributes, block numbers or folder placement; and compiler results that list only real diagnostics, so totals always match the compiler’s own count. Dozens more fixes and improvements since v3.15.2 — see CHANGELOG.md for the full list.
*V17 through V20 are supported for project work. V16 and older are detected and refused with a clear message. Only V19 is fully tested; the others are expected to work as TIA Portal maintains backward-compatible Openness APIs across versions.
Overview
TiaCommander is an MCP server that connects AI assistants to Siemens TIA Portal via the Openness API. It enables AI-assisted PLC programming, project management, library operations, hardware configuration, cross-reference analysis, and deployment — all through natural language.
Tested AI clients: Claude Desktop, Claude Code, VS Code (Copilot), Cursor, Windsurf, Codex CLI, Gemini CLI.
19 tools, 230 actions covering the full TIA Portal project lifecycle.
